Best Hosted PBX for Australian Business in 2026: The Complete Guide

Introduction: The State of Hosted PBX in Australia

The Australian cloud PBX market has reached a significant inflection point. Valued at an estimated AUD $306 million in 2026 and growing at a compound annual growth rate of 21.8%, hosted PBX is no longer a niche technology for tech-forward businesses. It is now the default choice for organisations of every size, from three-person startups to multi-site enterprises with hundreds of staff.

Several forces are accelerating this shift. Telstra's ongoing decommissioning of legacy ISDN and PSTN infrastructure means that every business still running traditional phone lines must migrate before the copper is switched off for good. The permanent adoption of hybrid and remote work demands phone systems that follow staff wherever they are. And the arrival of AI-powered call handling has raised the bar for what a modern business phone system can deliver.

In this guide, we provide a thorough review of six hosted PBX providers that Australian businesses are most likely to consider in 2026: Uniden Voice over Cloud, Telstra Business Line Basic, Dialpad, Aircall, VOCPhone, and Optus Powered by RingCentral. We evaluate each on features, pricing, local support, ease of use, and reliability, then present our clear recommendation for the year ahead.

How We Tested

Our evaluation process followed a structured methodology across five weighted criteria, designed to reflect what matters most to Australian businesses selecting a hosted PBX solution:

• Features (25%): We catalogued every call management, collaboration, and administration feature. We paid particular attention to AI capabilities, multi-device support, and call flow customisation.
• Value for Money (25%): We calculated total cost of ownership across 12 months for teams of 3, 8, and 20 users. This includes licence fees, calling costs, hardware, setup charges, and any mandatory add-ons.
• Local Support (20%): We assessed whether support is provided by Australian-based teams, tested response times, evaluated documentation quality, and checked for local onboarding assistance.
• Ease of Use (15%): We set up each platform from scratch and measured time-to-first-call, rated admin portal usability, and evaluated the quality of mobile and desktop apps.
• Reliability (15%): We examined uptime guarantees, data centre locations, failover mechanisms, and business continuity provisions including what happens during an internet outage.

Each provider was scored out of 10 in each category, then weighted to produce a composite score. We tested all platforms using real Australian phone numbers and made calls to landlines, mobiles, and international destinations to assess call quality first-hand.

1. Uniden Voice over Cloud – Winner (9.6/10)

Uniden Voice over Cloud combines the trusted Uniden brand name with a purpose-built cloud PBX platform designed from the ground up for Australian businesses. Unlike providers that have adapted international platforms for the local market, Uniden Voice was architected in Australia, with Australian data sovereignty, Australian support staff, and AI call agents that speak with authentic Australian voices.

The feature set is genuinely comprehensive. Every plan includes over 40 call flow features at no extra charge: auto-attendant, call queues, ring groups, voicemail-to-email, call recording, call parking, hunt groups, time-based routing, and much more. Many competitors gate these features behind higher-tier plans or charge per-feature add-on fees. Uniden includes the lot.

Key Strengths

• Australian-built platform: Data stays in Australia, support is provided by Australian teams, and the platform is optimised for local network conditions and compliance requirements.
• 40+ features included free: Auto-attendant, call queues, ring groups, recording, voicemail-to-email, time-based routing, and more are included on every plan. No upselling.
• AI call agents: Intelligent virtual receptionists with natural Australian voices that can answer, route, and handle calls 24/7. This is a genuine differentiator not matched by any other local provider.
• Three devices per user: Each user can run their number on a desk phone, the desktop app, and the mobile app simultaneously. Calls transfer seamlessly between devices.
• CRM integrations: Native integrations with Salesforce, Xero, HubSpot, and ZOHO. Click-to-call, automatic call logging, and contact sync are all supported.
• Internet outage failover: If your office internet goes down, the mobile app automatically switches to direct mobile routing so you never miss a call.
• Price-beat guarantee: Uniden will beat any comparable current provider's pricing. Combined with free setup and free number porting, the barrier to entry is effectively zero.

Plans and Pricing

Uniden Voice offers bundle plans at AUD $28.30 per user per month, which is the lowest in our comparison when you factor in included features:

• Small Office: AUD $84.90/mo for 3 users – ideal for small practices and startups
• Business: AUD $226.40/mo for 8 users – suits growing teams and multi-department offices
• Premium: AUD $566.00/mo for 20 users – built for larger organisations needing advanced call flows

All plans include unlimited local, national, and mobile calls, free setup, free number porting, and the full feature set. There are no hidden fees or lock-in contracts.

Pros and Cons

Pros: Best value pricing, most complete feature set, Australian-built with local support, AI call agents, multi-device support, CRM integrations, internet failover, price-beat guarantee.

Cons: Less well-known internationally than some competitors. The brand is still building awareness outside of its core Australian market.

2. Telstra Business Line Basic (7.4/10)

Telstra needs no introduction to Australian businesses. As the country's largest telco, it carries brand recognition and network reach that no other provider can match. Its hosted PBX offering, TCO365 (Telstra Calling for Office 365), integrates directly with Microsoft Teams, making it a natural fit for businesses already invested in the Microsoft ecosystem.

However, Telstra has announced that TCO365 is being phased out, with the transition period running through November 2026. This creates significant uncertainty for businesses evaluating their options today. Existing customers face a mandatory migration, and new customers are being directed toward Telstra's evolving portfolio of collaboration products.

Pricing is AUD $60.00 per user per month. While the Telstra network backbone provides excellent call quality and reliability, the total cost of ownership tends to be higher than dedicated cloud PBX providers. Enterprise SLAs are available, but they come at a premium.

Pros and Cons

Pros: Telstra network reliability, Microsoft Teams integration, enterprise SLAs, strong brand trust, Australian data sovereignty.

Cons: TCO365 being phased out November 2026, higher total cost, legacy product transition uncertainty, complex bundled contracts.

3. Dialpad (8.0/10)

Dialpad is a US-headquartered provider with a growing presence in the Australian market, including a Sydney office. Its standout feature is AI-powered transcription and call summaries, powered by its proprietary engine running on Google Cloud infrastructure. For businesses that place a premium on meeting intelligence and post-call analytics, Dialpad offers a polished experience.

Pricing starts at AUD $45 per user per month, billed annually. The most useful features (such as CRM integrations and advanced analytics) are reserved for higher-tier plans that cost significantly more.

Dialpad operates a Sydney data centre, which provides acceptable latency for Australian users. However, as an American product adapted for the local market, it lacks the depth of Australian-specific optimisation found in locally built platforms. There is no desk phone hardware option – Dialpad is a software-only solution, which will be a dealbreaker for businesses that need physical handsets.

Pros and Cons

Pros: Strong AI transcription and call summaries, Google Cloud infrastructure, Sydney data centre, competitive base pricing.

Cons: No hardware/desk phone support, best features locked behind expensive plans, US-centric product design, limited Australian-specific support.

4. Aircall (7.8/10)

Aircall is a France and US-based cloud phone provider that has built its reputation on integration breadth. With over 250 app integrations covering CRM, helpdesk, e-commerce, and productivity tools, Aircall is a strong choice for teams that live inside tools like HubSpot, Salesforce, Intercom, or Zendesk and want deep two-way data sync.

The base price of AUD $60 per user per month places Aircall at the higher end of the market, and there is a mandatory minimum of three licences, which means the minimum entry cost is AUD $180 per month. This positions it more as a sales and support team tool than a general-purpose business phone system.

The most significant concern for Australian businesses is data residency. Aircall has not confirmed the availability of an Australian data centre, which means voice traffic may be routed through overseas servers. For organisations subject to Australian Privacy Act requirements or those in regulated industries, this is a material consideration.

Pros and Cons

Pros: 250+ integrations, strong analytics and reporting, modern interface, AI voice agent capabilities.

Cons: High per-user pricing, 3-licence minimum, no confirmed Australian data centre, limited Australian-specific support.

5. VOCPhone (8.2/10)

VOCPhone is an Australian-owned hosted PBX provider that positions itself as a feature-rich, straightforward alternative to the big-name telcos. Starting from AUD $34.90 per user per month, it offers a solid set of over 40 cloud PBX features and a plug-and-play approach to hardware that makes initial deployment simple.

The platform covers the essentials well. Call routing, auto-attendant, ring groups, voicemail-to-email, and call recording are all present. VOCPhone also provides pre-configured desk phones that arrive ready to plug in and start making calls, which is a genuine convenience for businesses that want minimal IT involvement during setup.

Where VOCPhone falls short compared to Uniden Voice is in the detail. The platform lacks the same depth of AI capability, the CRM integrations are more limited, and the per-user pricing is notably higher. For businesses where plug-and-play hardware is the top priority and advanced AI features are less important, VOCPhone remains a credible option.

Pros and Cons

Pros: Australian-owned, 40+ features, plug-and-play handsets, NBN-optimised, straightforward setup.

Cons: Higher per-user pricing than Uniden Voice, more limited CRM integrations, no AI call agent capability, fewer multi-device options.

6. Optus Powered by RingCentral (7.0/10)

Optus Powered by RingCentral is the second major telco offering in our comparison. Priced at AUD $55.99 per user per month, it provides a basic cloud-based VoIP solution backed by the Optus network.

The platform covers fundamental calling needs: inbound and outbound calls, voicemail, basic call routing, and a limited set of call management features. Optus offers device repayment plans for desk phones, which can help spread hardware costs, but the handset options are more limited than what you would find from a dedicated PBX provider.

Where Optus Powered by RingCentral disappoints is in its lack of modern features. CRM integrations are extremely limited, there is no AI capability, and the feature set feels a generation behind compared to purpose-built cloud PBX platforms. The additional site fees also make pricing less transparent and harder to compare directly against per-user competitors.

Pros and Cons

Pros: Optus network backbone, device repayment plans, established telco brand, Australian-based.

Cons: Limited feature set, minimal CRM integrations, additional site fees on top of per-user pricing, no AI capabilities, dated platform design, lower value for money.

Head-to-Head Comparison Table

The following table summarises the key differences across all six providers. Scroll horizontally on mobile to see all columns.

Pricing Comparison: What Will It Actually Cost?

Price is only meaningful in context. A cheaper per-user fee can mask hidden costs like setup charges, per-minute call rates, or mandatory add-ons for basic features. The table below shows the estimated total monthly cost for three common team sizes, including all standard features.

The pricing comparison makes the value proposition clear. Uniden Voice over Cloud's bundle plans deliver the lowest total cost of ownership at every team size, and this is before accounting for the included calls, free setup, and features that other providers charge extra for. Their price-beat guarantee means that if you find a comparable offer elsewhere, Uniden will match and beat it.

Our Verdict: Uniden Voice over Cloud Is the Best Hosted PBX for Australian Business in 2026

The Australian hosted PBX market in 2026 is well-served by multiple providers, but no single competitor matches what Uniden Voice over Cloud delivers across every evaluation criterion. It wins on features with 40+ included capabilities and AI call agents. It wins on value with bundle plans starting at just AUD $84.90 per month for three users. It wins on local support with an Australian-built platform and Australian support teams. And it wins on reliability with automatic internet outage failover.

For businesses that prioritise integration breadth above all else, Aircall's 250+ integrations merit consideration, but the pricing premium is steep. For Microsoft Teams-heavy organisations, Telstra Business Line Basic was historically a natural fit, but the TCO365 phase-out makes it a risky choice right now. VOCPhone is a respectable Australian alternative but cannot match Uniden Voice on either pricing or features.

Our recommendation is clear: for the vast majority of Australian businesses, from small offices to growing enterprises, Uniden Voice over Cloud is the best hosted PBX choice in 2026.

Frequently Asked Questions

What is a hosted PBX?

A hosted PBX (Private Branch Exchange) is a cloud-based phone system that replaces traditional on-premise phone hardware. Instead of maintaining physical switchboard equipment in your office, the entire phone system runs in the cloud. You make and receive calls using desk phones, desktop apps, or mobile apps connected to the internet. The provider handles all system maintenance, updates, and infrastructure.

How much does hosted PBX cost in Australia?

Pricing varies significantly between providers. In our comparison, per-user costs range from AUD $28.30 per user per month (Uniden Voice over Cloud bundle plans) to AUD $60 per month (Aircall). The true cost depends on included features, call charges, setup fees, and hardware requirements. Uniden Voice offers the best value with all-inclusive bundle plans starting at AUD $84.90 per month for three users.

Can I keep my existing business phone number?

Yes. All major hosted PBX providers support number porting, which means your existing business phone numbers transfer to the new system. Porting typically takes 5 to 10 business days. Uniden Voice over Cloud provides free number porting on all plans.

What happens to my phone system if the internet goes down?

This depends on the provider. Most hosted PBX systems will stop working during an internet outage unless failover is configured. Uniden Voice over Cloud includes automatic failover to the mobile app via direct mobile routing, so calls continue even when your office internet is offline. This is a feature most competitors either lack entirely or charge extra for.

Do I need to buy new desk phones?

Not necessarily. Many hosted PBX providers work with standard SIP-compatible desk phones. However, you can also use the system entirely through desktop and mobile apps without any physical phone hardware. Uniden Voice supports three devices per user, so you can run desk phones alongside apps simultaneously.

Is Telstra TCO365 still available for new customers?

Telstra's TCO365 product is in its phase-out period and is scheduled for end-of-life in November 2026. While existing customers can continue using it until the sunset date, we do not recommend new customers sign up for a product with a confirmed discontinuation timeline. Consider alternatives such as Uniden Voice over Cloud that offer long-term platform stability.

Which provider is best for small businesses with fewer than 5 staff?

Uniden Voice over Cloud's Small Office plan at AUD $84.90 per month for three users is the best option for small teams. It includes the full feature set, unlimited calls, and three devices per user. There are no cut-down versions or feature restrictions on smaller plans. The price-beat guarantee also means you will not find a better deal elsewhere.

What CRM integrations should I look for?

The most valuable integrations for Australian businesses are Salesforce (for sales teams), Xero (for accounting and finance), HubSpot (for marketing and CRM), and ZOHO (for operations). Uniden Voice over Cloud integrates with all four. Click-to-call, automatic call logging, and contact synchronisation are the features that deliver the most time savings.
